ADUM7701-8BRIZ

ADuM7701 is a high performance, second-order, Σ-Δ modulator that converts an analogue input signal into a high speed, single-bit data stream, with on-chip digital isolation based on Analog Devices, Inc., iCoupler® technology. The device operates from a 4.5V to 5.5V power supply range(V DD1) and accepts a pseudo differential input signal of ±250mV (±320mV full-scale). The pseudo differential input is ideally suited to shunt voltage monitoring in high voltage applications where galvanic isolation is required. The analogue input is continuously sampled by a high performance analogue modulator and converted to a ones density digital output stream with a data rate of up to 21MHz. Typical application includes shunt current monitoring, AC motor controls, power and solar inverters, wind turbine inverters, analogue-to-digital and optoisolator replacement.
